c++ Carriage Return Line Feed long string followed by a shorter string

I have an application which I want to print status messages with. However, sometimes it occurs that a shorter status message follows a longer status message, which leads to the following situation:

Long message:

this is the long status message which is longer than the short one

Shorter message:

This is the short status messagewhich is longer than the short one
//this one should end here      ^

The code I'm using is:

cout << StatusMessage << '\r';

How can I overcome this problem and firstly erase the whole line before printing the new line? Preferably with a cross platform solution, but for now I'm working on Windows

Note: I already tried to overwrite the line with \b or spaces, however this may result in a multiple line cleaning which removes the functionality of my \r approach.

I'd use '\b' (backspace) repeatedly in the length of the former output for your case. It seems to be pretty standardized:

cout << StatusMessage << '\r';
cout << std::string(StatusMessage.size(),'\b');
